To all whomit may concern shown in Fig. 1 taken perpendicular to the 13c it known that I, FRANK B. KEaLL, a subject of the King of England, residing at;

Leicester, in the county bf Leicester, Eng-'1 'land, have invented certain Improvements in Edgesetting Machines, of which the following description,in connection with the accompanying drawings",- is a specification, like reference characters on the drawings indicating like, parts in the several figures.

This invention relates to edgesetting machines used in the manufacture of boots and shoes, and pertains particularly to the edge setting tool which is rapidly oscillated or reciprocatedin Contact with the edge of the shoe. j The angle between the'edge and the tread face of a shoe sole varies considerablyindifferent styles of shoes, and varies to some extent even in the same shoe, owing to inaccuracies inthe edge-trimming. The ordinary edge setting tool compels theoperator to hold shoes of difle'rent styles at di'iierent angles while setting their edges, which is inconvenient, and it also misses portions of irregularly trimmed sole edges even when the operator has struck the general angle.

It is the purpose of this invention to meet this difficulty by providing an edge setting tool which will operate on soles differing from one'another'in the inclination of their sole edges, and also upon sole edges which are differently inclined in diiferent portions, which will do the work more etticiently and better than heretofore, and which can be readilyadjusted or removed from the machine without interfering with the adjust-- ment. 1 I

Fig. 2is'a-plan of the device as line 22, ofjFig. 1, the stitch-wheeling disk being removed. Fig. 3 is a section on the line3+3 of Fig. 1. Fig. 4 is a side eleva- EDGE-SETTING MACHINE.

which fits within the slot 3. [The body 4 carries the head 5, which is wider than the body t and overlaps the holder 2. 'T he front of the head 5 carries the edge setti'ngirou' 6, which has the lips 7 at its upper and lower portions, of any desired for 1n,'-to set the cornersof the sole edge. The head- 5' also carries the stitch-wheeling disk 8, pivotally mounted at 9. I v

The lower faces of the lateral portions of thehead 5 have recesses 10 which have sharp corners 11 at their front and contact surfaces 12 'at theirrear. The walls of the holder 2 which inclose the slot 3 are formed with knife edges 13 and cylindrical contact surfaceslt. The knife edges 13 fit in the corners ll and the surfaces- 12 can pivot about theedges'18, and remain in contactwith the surfaceslt which are centeredat- 13. The edge setting iron is thus capable of adjustment about a horizontal axis at 13. The rear end of the body 4 has a slot 15, by means of whichthe iron is held in adjuste position. i g

Threaded inthe holder '2 isa screw 16, which carries on its upper end a sleeve 17,

having a lateral arm 18, which projects into the slot 15, but does not fill it from side to side. The rotation of the screw 16 will thus adjust the sleeve 17 and the arm 18,

andwill rotate the body 4 and iron 6 into suitable position to fit the general inclina tion of the sole edge which is to be operated upon, and the loose fit of the arm 18 in the slot will permit a small oscillation on each side of a mean position to fit varying inclinations of the same sole edge.

Mounted'on a pin 19 is a spring 20 the upper end of which is slidably mounted in an arm 21 on the sleeve 17, and holds the arm 18 in the slot 15. thespring 20 bears 0111a friction: plate 22 pivoted on the pin 19' and held in contact with the screw 16 by the spring 20. This I Thelower end of the spring 20, until the arm 18 is turned out of the slot 1 5, whereupon'theibody 4 can be tipped up until thesurfaces 12' and 1t separate. permitting the removal of the bodv 4 and itsiron 6 from the holder 2. and the substitution of another of like formed body, while'preserving the adjustment.

In the'second form, shown in Figs. 4 and 5, the screw 24 is mounted in the rear end of the slot 3 inthe' holder' 2,1andcarries a stop arm 30 which cooperates with a recess 31 in the side wall of the holder 2, and, which limits the swing of the screw 24 aboutthe axis of shaft 29. A plunger 32, spring pressed by the spring33 in, the recess 34.

holds the screw 24 and its sleeve25in forwardposition and its arm 26 in the slot 15,

. but by pulling back the screw against the the slot 15 and the body 4 and its iron 're-- spring 33 the arm'26 can be drawn out of leased, without disturbing the adjustment.

Aplunger 35 is held againstjthe reduced portion 28 by the spring 36 in the hollow screw 37, which is mountedin' the shaft 29, and by friction prevents accidental rota tion'of the screw 2 Having described-my invention, what I claim as new and desire to secure by United States Letters Patents is 1.
